IMPRGVEMENT IN PROCESSES GF GRANULATING SUGAR.

Specification forming part of Letters Patent No. 132,511, dated October22, 1872.

.and State of Tennessee, have invented a new and Improved Process forGranulatin g Sugar, of which the following is a full, clear, and exactdescription The said process is as follows: We run the juice from themill through white clay or fine white sand, whereby all the fibers orparticles of cane are caught. It is then conveyed in pipes to thesettling-box, from which it is let onto the first section and front endof the evaporator, where it is heated to boiling and skimmed off. It isthen passed to the second section and boiled to about 25 density, orsweet; thence to the third and finishing section. When this is reachedwe add about one pint of tannin (made preferably from white oak, theliber or inner bark being taken off) to each gallon of sirup. As thetannin is added the glutinous and feculent matters are separated fromthe saccharine, brought to the surface, and thrown off, leaving thesirup a clear golden yellow color. The boiling is continued until 36density, or sweet, is attained, when machine, which separates and driesit at the I same time, and a continued practical test has demonstratedthat about five pounds of sugar to each gallon of sirup can be realizedwith a residuum of six pounds of good sirup.

Having described our invention, we claim The process herein describedfor granulating sugar.

In testimony whereof we have hereunto signed our names.
